Pokemon AU for my OCs

I've wanted to make my own fanmade Pokemon game for a long time, and now that I have the resources to make the game, I kinda realized... I need to learn the program and stuff. So, I decided I would make a quick and basic game to learn the basics and get to know the software I'm using. So... then an idea came to me.

What if... the characters are my OCs? I had already decided I wanted to make myself the Champion of the game(If you've never played a Pokemon game, that's the final boss.), however it didn't come to me until later when I was working on designing this AU version of my sona that I could use my already existing OCs as the characters! That saves a lot of the character designing aspect as all I have to do is redesign them to fit their roles.

The player character will be completely original though, and I may make new characters for the rival(s) and evil team.
